4, operating system: the control that is mainly used in hydraulic system.Comprise operating room 9, various pilot-actuated valve 19, big flow guiding valve 20, cable cupboard 50, brake valve 21, overflow valve 18, switchbox 8.Annex comprises that platform assembly 14, preceding very heavy 13, back are very heavy 1, girder 15, etc. composition.
This hydraulic energy-accumulating workover rig, the course of work is as follows:
With special-purpose vehicle this hydraulic energy-accumulating workover rig holder is carried on the back and to specify well head, four very heavy below the good wooden pressure blocks of pad, very heavy 13 before rising, back is very heavy 1, is the balance and stability that guarantees equipment work, very heavy 1 Breadth Maximum in back can be transferred to 3600mm.
Start pump group 7, make system pressure reach 16MPa; Inspection oil pump and hydraulic system are guaranteed no abnormal phenomenon; And brake valve is placed on normal danger, guarantee that master cylinder 22 is failure to actuate; Operation amplitude oil cylinder 10 control valves are holded up master cylinder 22 and accumulation of energy cylinder 23, and girder 15 girder pin bolts 16 are fixed, with 17 lockings of girder 15 girder bearing pin nuts.
This hydraulic energy-accumulating workover rig Hoisting System mainly is made up of master cylinder 22, pulley assembly 37, overhead traveling crane assembly 36, rod assembly 29, weight indicator 12 etc.Movable pulley is contained in the master cylinder top, and fixed pulley 41 is installed on the girder 15, and master cylinder is the critical component of equipment, is bearing the work that plays drain line, and movable pulley fixed pulley and overhead traveling crane assembly are used for promoting and transferring tubing string.Rod assembly 29 is used for fixing with the leveling girder, after pin is put on, the pull bar hold-down nut should be locked.
With reference to accompanying drawing 3, master cylinder 22 is divided into main chamber A and auxiliary oil pocket B and the auxiliary oil pocket C of rising.As A, B, when C three chambeies enter hydraulic oil simultaneously, this moment, the lift minimum was the I shelves; When A, B two chambeies enter hydraulic oil simultaneously, and lift increases to the II shelves this moment when being connected with the oil return pipeline in the C chamber; When A, C two chambeies enter hydraulic oil simultaneously, and lift increases to the III shelves this moment when being connected with the oil return pipeline in the B chamber; When the A chamber enters hydraulic oil, and B, lift was the IV shelves to the maximum this moment when C two chambeies were connected with the oil return pipeline; See master cylinder figure.
For tubing string is conveniently tripped out, master cylinder 22 design maximum strokes can reach 5500mm, lifting hook range 11000mm.
The operating system of this utility model is made up of various control valves, mainly finishes in operating room 9 inside.Form by A, B, C chamber electromagnetic priority valve 19, big flow guiding valve 20 and brake valve 21.
A, B, C chamber electromagnetic priority valve are controlled three oil pockets of A, B, C of master cylinder respectively by big flow guiding valve, finish the landing of master cylinder.The function of brake valve is the pressure source that switches on or off master cylinder A chamber.When the stop motion of needs hook, turn off brake valve rapidly, hook can be stopped at an arbitrary position and stop this moment; When the needs hook is up, handle pilot valve in the time of the fuel feeding of master cylinder A chamber, open brake valve.When the needs master cylinder is descending, handle pilot valve the A chamber is connected with the oil return pipeline, open brake valve simultaneously; When needs stop, closing brake valve.
With reference to accompanying drawing 4, the accumulation of energy cylinder 23 and master cylinder 22 contour being installed in simultaneously on the girder 15 arranged side by side of this utility model, holding fluid cylinder is the float-type hydraulic cylinder, by cylinder body 23.6, inner float 23.3, hydraulic system interface 23.1, down put switch 23.2, outside buoy 23.4, on put switch 23.5 and nitrogen interface 23.7 etc. and form.Holding the inner float of fluid cylinder is the transmission unit of liquid and gas, also is a gas-liquid fence cell simultaneously.Cylinder body top is connected with the elevated pressure nitrogen gas bag, and the bottom is connected with hydraulic system.Cylinder body top is provided with some switches, the bottom is provided with down some switches, when float is up when contacting some switches, it is up that the connection electromagnetic valve stops float, the accumulation of energy cylinder is preserved energy, when the hook assembly need increase pulling force, the energy that remains in the accumulation of energy cylinder in time imported in the master cylinder, and the buoy that shows the float activity is housed between the lower interface on the cylinder body outside.
The float-type hydraulic cylinder device, be to hold in the fluid cylinder float under the acting in conjunction of high pressure nitrogen and hydraulic system according to system's needs and free floating, at first the hydraulic oil of pump group enters and holds hydraulic cylinder when master cylinder is descending, so that use when needing.Secondly when master cylinder and other executive components were not worked, the hydraulic oil of pump group entered and holds the fluid cylinder storage.Once more when following drain line, when oil pipe is transferred to certain depth, when transferring to 2000 meters as the oil pipe of ￠ 73mm, can only open this moment little pump or turn on pump just can not reach the purpose of time drain line.
Therefore the float of float-type hydraulic cylinder and cylinder bucket are non-contact types, can not produce scuffing of cylinder bore or phenomenon such as stuck.
Workover rig is not to be fixed on the carrier loader, has special-purpose carrier vehicle holder to carry on the back assigned address during work, carries on the back the whole device of support that four supporting legs can be stable behind the assigned address.Especially the vehicle holder back of the body is convenient in order to guarantee balance of plant, and its rear support leg width is adjustable wide.After support oil cylinder was propped, carrier loader drove away.
